Improvements to SpECTRE's Computational Domain for Binary Black Hole Simulations

In order to interpret gravitational wave signals received by future gravitational wave detectors, we will need models of binary black hole mergers with much higher accuracy than we have today. SpECTRE is a next-generation numerical relativity code being developed to address this need. An important part of producing high accuracy models of binary black holes is the careful construction and tuning of the computational grid on which our simulations run. In this talk, I will discuss SpECTRE's binary black hole computational grid and changes we've made to improve the robustness and accuracy of our simulations.
